Lattice Block Structures for Missile Structural Components Navy SBIR FY2009.1 Sol No.: Navy SBIR FY2009.1 Topic No.: N091-045 Topic Title: Lattice Block Structures for Missile Structural Components Proposal No.: N091-045-0593 Firm: CalRAM, Inc. 2380 Shasta Ave, Suite B Simi Valley, California 93065-1858 Contact: Dave Ciscel Phone: (805) 844-7823 Web Site: www.calraminc.com Abstract: Lattice Block Structures (LBS) are used to produce parts with higher specific stiffness than a solid but are difficult to produce. Electron Beam Melting (EBM)technology is capable of building LBS in a variety of configurations directly from a computer file using much thinner and stronger ligaments or wall sizes than cast LBS. EBM LBS are lighter, can be produced faster, and in more complex shapes than conventionally produced LBS. The flexibility of EBM allows a designer to tailor properties in orientations as needed and still reduce component weight. EBM titanium LBS are ideal for Naval applications as the material is extremely resistant to corrosion. Benefits: Designers will have the ability to tailor specific stiffness and weight, and change it as required throughout a part. Design changes and upgrades implemented as easily as changing a computer file. Commercial applications for tailorable specific stiffness range from higher performing military hardware to driver faces on golf clubs. Return
